Most backup utilities are GUI wrappers around rsync and end up making rsync more difficult to use, instead of easier. For example backintime, flyback, luckybackup and a zoo of others.

So, do read the rsync man page. A typical backup script is a one liner and making that 'simpler' with a GUI wrapper is usually not possible.

Indeed most backup gui's are based on rsync, however sometimes I think a well designed gui can be useful and I think Luckybackup is one such application. That is why I'd recommend it as an easy to use backup tool. When one is more confident with the command-line then I'd obviously recommend rysnc much as I'd recommend yum over gui software management tools. For those new to *nix then gui's offer the comfort zone often needed
